It is no quick way to earn money in domaining if you are after retail pricing (bigger bucks). List the name on all marketplaces (Afternic, DAN, Sedo) and hope for the best. Depending on the name maybe do some outbound marketing yourself to push it.
If it is brandable submit to Squadhelp and/or BrandBucket to see if they approve it for sales (no sales guaranteed if they do but might improve your odds).
If you want to liquidate (and the name is decent) to other investors put it up for auction here with 1$ start or some other marketplace like GoDaddy, SAV, NameCheap etc.
